FLYING-MACHINE.

Specification of Letters Patent.

Patented Dee. 2o, 1910.

Application filed July 15, 1909. Serial No. 507,849.

To all whom t may concern.'

GEANT, a citizen of the Unit-ed States, residing at East Orange, in thecounty of Essex and State of l\"ew.J.ersey, have invented new and usefulImprovements `in Iflyingfacliines, of which the following is aspecification.

This invention relates to flying machines or airsliips of the heavierthan air type; and the principal object of the invention is to providemeans whereby the stratum of air disposed directly. adjacentv to theupper sides 'of the lifting planes may be eX- hausted and utilized -inthe propulsion of.

the machine, thus enabling the latter to rise more readily than 'whensubjected to" the direct pressure of the superposed air.v

Further objects of the invention are to simplify and improve theconstruction and operation of this class of devices.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same `con-l sists inthe improved construction and novel arrangement -and combination ofparts which will be hereinafter fully described and pointed out intheappended claims.

In the accompanying drawings has been lillust-rated a simple andpreferred form of `l-'the invention; it, being however, understood thatno limitation is necessarily made to the precise' structural detailstherein exhibited,-

but that changes, alterations and modifica- `tions within the scope ofthe invention may be made when desired.

Inu the drawings: Figure l is a top plan view, showing the invention.Fig. 2 is a .longitudinal sectional view of the same.

Fig. 3 is a transverse sectional view taken I4 1 l. l orresponding partsin the'several views 'are denoted by like characters of reference. i i

the. construction of the limproved devic'ejfhthere 1s provided an airchute org-casing 5,w': ch may be approximately circular in crosssection;said chute, which isprovided wi th.a"downwardly and rearwardly curvedoriiriclined bottom `Gzisopen at the top and at .therear end for thepassage of air. A djacent to the open rear end'of the chute are apropeller wheel 9 is supported for rotation. Means are to be providedfor driving the propeller wheel 9 but said means have not beenillustrated in the drawing and it is evident that a suitably disposedmotor of any suitable construction may be utilized for this purpose.

suitably connected with and extending laterally from the upper edges ofthe chute 5 are the front and rear planes lO-ll and the side planes l2which latter may be pro-y vided with extensions 13 connected therewith.The tail piece or rudder 14 is hingedly connected with the rear edge ofthe 4rear plane fr? lTliecperation and advantages of this invention willbe readily understood from the foregoing description taken in connectionwith the appended drawings. It is obvious that when tlxe'propeller wheel9 is in 'motion 5 in advance of said propeller wheel, and that the airexhausted from the chute will be replaced by air from the upper surfaceof of the air current being indicated by darts, in Figsf l and 2 of thedrawing. Itis obvious that the pressure of the superposedy air 'beingthus removed, the machine will rise less power than would otherwise b ethe case.

It will be understood that no limitation is Aintended with regard to theshape or the specific construction of the air chute, but

that the exact formation of the same may be varied within the scope ofthe appended claims. Havingl thus described the invention, what isclaimed is* l. In aliying machine7 an air chute of apa partial vacuumwill be created in the chute more readily, and with the expenditure of B1 1 I M V b l provided bearings wherein the shaft 8 of l e it {nown tiatoR'rIMER Anthe laterally extending planes, the direction" vaoproxilnately circular cross section and havand ut the rear e11d,'fr0nt,rear and sidey shaft adjacent to the open rear und of the plane$connooted with and extending laterally from the upper edges of thechute, lateral extensions Connected with 5 planes, a rudder connectedlingedly with tho roar plane adjacent to the rear edge of y the latter,and a propellery Wheel supported for rotation upon u longitudinallydisposed chiite. 1.0 ln tclnnony whereof I, ulix my Slgnaturc the side'lin prosencolof two Witnesses.
